java - 即使没有依赖关系，Spring Bootrabbitmq 连接也被拒绝

Question

当从 springinitializer 创建项目时，我添加了rabbitmq 依赖项，但后来决定不使用它后将其删除。现在，在运行应用程序后，我仅收到一次连接拒绝错误。它不会影响其余 api 的使用/功能，并且工作得很好，但没有人希望他们的应用程序出现错误，即使它不会引起问题。我清理并重建了该项目，但它不起作用。可能与执行器的健康检查有关，但找不到解决办法。这是异常消息；

Answer 1

1. 确保确实已从 pom.xml/build.gradle 文件中删除“spring-boot-starter-amqp”。
2. 发布完整的依赖项部分，以便我们可以查明是否还有另一个依赖项在其中引入“消息传递”。
